Enable macOS M1 wheel builds

This commit contains fixes for `ml-metadata`'s build setup to enable wheel builds on macOS M1.

The core build files have not been touched except for version increments of Bazel dependencies, and for `mariadbconnector-c`, whose build file needed to be updated to support
the latest version.

Several dependencies were upgraded to newer versions, with the update policy being "as recent as possible without breaking changes". A few gRPC dependencies were eliminated from
`ml-metadata`'s workspace to avoid friction on subsequent gRPC updates (this includes e.g. `protobuf`, `zlib`).

This change allows for M1 wheel builds without more external system dependencies outside of Bazel - the used build definitions contain M1 capabilities for sufficiently new versions of Bazel.
